Inconel 718 plus UNS N07818 Precipitation Hardened Nickel-base Superalloy

Inconel 718Plus alloy (UNS N07818) is a precipitation hardened nickel-base material that exhibits high temperature tensile strength and stress rupture performance. This alloy is designed to have the high temperature capability and thermal stability of Waspaloy alloy while retaining the processing characteristics of 718 alloy. It is double vacuum melted (VIM/ESR/VAR). This VIM/VAR process ensures excellent microcleanliness and tight compositional control. Triple melting, with electroslag remelting between the VIM and VAR operations, minimizes the possibility of macrosegregation, increases microcleanliness, and is preferred for premium quality jet engine rotating component applications. Inconel 718Plus alloy has at least a 100°F (55°C) operating temperature advantage over 718 alloy. 718Plus alloy also has advantages over Waspaloy and other higher temperature capable, nickel-base alloys due to its higher strength, superior formability, better wear resistance, and a resistance to weld cracking. 718Plus alloy is a lower cost option than Waspaloy or Rene 41 alloy due to its lower intrinsic raw materials cost and improved hot workability which provides higher material yields, resulting in a lower cost finished part.
